Market size
The global building automation systems market was valued at $87.85 billion in 2025. Other current estimates place the 2025 market between $92.57 billion and $109.5 billion, reflecting differences in scope and methodology.[68][69][70]
Forecast & CAGR
Fortune Business Insights forecasts growth from $94.5 billion in 2026 to $184.42 billion in 2034, representing an 8.7% CAGR. The Business Research Company projects a 13.1% CAGR from 2026 to 2030, reaching $204.14 billion.[68][71]
Market share & regions
North America accounted for 34.5% of the global building automation systems market in 2025 in Fortune Business Insights' estimate. Europe represented 34.5% of the related building automation and controls market in 2025, while Asia-Pacific is identified as the fastest-growing region in multiple forecasts.[68][69][72]
Segmentation
HVAC controls were the largest system category, accounting for 38.51% of 2025 revenue in Mordor Intelligence's market definition. Hardware held 48.43% of 2025 revenue, while the market is commonly segmented into hardware, software and services and into residential, commercial and industrial end users.[72][73][68]
Key players & concentration
Major suppliers include Honeywell, Johnson Controls, Schneider Electric, Siemens, ABB, Trane Technologies, Carrier, Bosch and Mitsubishi Electric. In residential building automation, Honeywell held more than 26.5% of 2024 market share and the top five suppliers collectively held 54.4%, indicating materially higher concentration than the broader market.[74][71]
Pricing
A U.S. Department of Energy-backed survey of 12 vendors found median retrofit costs of $2,300 per building for a networked thermostat solution and $4,100 per building for advanced rooftop-unit controls, including materials and annual subscription costs. Pricing varies substantially with building size, equipment count, integration scope and commissioning requirements.[75]
Trends, drivers & challenges
Growth is being driven by energy-efficiency requirements, net-zero targets, retrofit demand, cloud analytics, wireless controls and AI-enabled optimization. Key challenges include integration with legacy HVAC infrastructure, interoperability across proprietary systems, cybersecurity, skilled-labor shortages and proving payback to building owners.[72][76][41]
